A composite panel includes a substrate-less touch sensor panel and a first coupling member coupled to one surface of the touch sensor panel via a first adhesive layer.

Composite panel

A touch sensor includes a first sensing electrode unit formed on a substrate in a first direction and a second sensing electrode unit formed on the substrate in a second direction crossing the first direction. A plurality of micro-etched patterns are formed on a boundary of unit transparent electrodes constituting the first sensing electrode unit and the second sensing electrode unit. The unit transparent electrode has a shape in which a portion of a curve connecting vertices of a polygon is removed, and adjacent unit transparent electrodes are electrically connected to each other. It includes a segmental pattern dividing the first or second sensing electrode unit into two or more areas.

Touch sensor including segment pattern dividing sensing electrode

A touch sensor comprises a first electrode layer, a second electrode layer, and an insulation layer. The first electrode layer includes first main electrode cells connected and arranged in a first direction and second auxiliary electrode cells separated from the first main electrode cells and arranged separately in a second direction on the same lower plane. The second electrode layer includes first auxiliary electrode cells arranged separately in the first direction and stacked and connected to the first main electrode cells while having the same pattern as the first main electrode cells and second main electrode cells separated from the first auxiliary electrode cells, connected and arranged in a second direction, and stacked and connected to the second auxiliary electrode cells while having the same pattern as the second auxiliary electrode cells, on the same upper plane. The insulation layer is formed between the first electrode layer and the second electrode layer.

Touch sensor

A touch sensor includes a base layer; an electrode layer including, on the base layer, first array sensing cells connected and arranged in a first direction and second array sensing cells spaced apart from the first array sensing cells and arranged spaced apart in a second direction, the first and second sensing cells being provided with dummy holes; an insulation layer formed on the electrode layer and being provided with contact holes connecting the neighboring second array sensing cells in the second direction; and bridges formed on the contact hole and the insulation layer to electrically connect the neighboring second array sensing cells.

Touch sensor and method of manufacturing the same

The present invention provides a method for manufacturing a flexible display device comprising a touch sensor, capable of controlling process dispersion and inhibiting cracks during the transfer of the touch sensor.
